Leaf Anatomy: Pre Lab
Pre-Lab:
- An aquatic plant is an example of a: a. hydrophte b. mesophyte c. xerophyte
- A cactus is a good example of a: a. hydrophte b. mesophyte c. xerophyte
- An oak tree is a good example of a: a. hydrophte b. mesophyte c. xerophyte
- A dandelion is a good example of a: a. hydrophte b. mesophyte c. xerophyte
- A wetland is a good place to find a: a. hydrophte b. mesophyte c. xerophyte
- A rocky outcrop is a good place to find a: a. hydrophte b. mesophyte c. xerophyte
- The forests at CSB & SJU would be good places to find a: a. hydrophte b. mesophyte c. xerophyte
- Xerophyte leaves will have a (thicker/thiner) cuticle
- Xerophyte leaves will have stomata (raised above the epidermis/sunken in chambers).
- Xerophyte leaves will have (more/fewer) layers of epidermis
- Xerophyte leaves will be (thinner/thicker)
- Xerophyte leaves will have (less/more) air space
- Xerophyte leaves will be (flat/coiled).
- Xerophyte leaves will have stomata (on the lower side of the leaf/on the upper side of the leaf).
- Mesophyte leaves will (be more similar to hydrophyte leaves/more similar to xerophyte leaves/show intermediate features between hydrophyte and mesophyte leaves)
4. For each of the three leaves below, indicate which is a hydrophyte, mesophyte, and xerophyte.
